    Adapter / Wall connector for duct D150 – 300x300 mm, white, steel, for ventilation systems

    Adapter / Wall connector for duct D150, designed for attaching a circular duct to a flat surface – wall, ceiling, partition, or other surface. It is a 300x300 mm steel ventilation connector with a 150 mm mounting diameter, used in ventilation systems when a neat connection of a circular duct to a surface is required.

    Main concept:
    This wall connector allows for convenient and secure attachment of a D150 circular duct to a wall, ceiling, or other flat surface. The steel construction with a white polymer enamel coating provides a neat appearance and is suitable for various ventilation and air distribution systems.

    Working principle

    The wall connector is used as a transition and mounting element between a circular duct and a flat surface. The connector is screwed to the wall, ceiling, or other structure, and a D150 duct pipe or other compatible ventilation system element is connected to the circular part.

    The wide 300x300 mm plane helps stabilize the connector on the surface, while the 150 mm circular connection allows for attaching standard-diameter ducts. The white polymer enamel coating provides a clean look and helps protect the steel from environmental factors under normal operating conditions.

    Why is a wall connector for a duct needed?
    A wall connector is used when a circular duct needs to be neatly connected to a wall, ceiling, or flat surface. It helps form a secure connection point and simplifies duct installation within a ventilation system.

    Applications

    • Residential ventilation systems – for connecting air supply or exhaust ducts.
    • Utility and auxiliary rooms – for mounting ventilation pipes to walls or ceilings.
    • Workshops and technical areas – where simple D150 duct connection to a surface is required.
    • Commercial premises – for mounting ventilation system components.
    • Recuperation or general ventilation systems – as a connecting element between the duct and the surface.

    Practical installation example

    For example, the wall connector is mounted on the wall or ceiling of a technical room. The flange is screwed on, and a D150 circular duct is attached to the circular connector. This forms a neat and stable ventilation duct connection point.

    This solution is suitable when ducts need to be connected to a wall, ceiling, ventilation opening, box, or other flat construction.

    Pros

    • D150 diameter – suitable for standard 150 mm circular ducts.
    • 300x300 mm flange – convenient mounting to walls, ceilings, or other surfaces.
    • Steel construction – a more robust solution than plastic alternatives.
    • White color – looks neat in bright technical or residential rooms.
    • Polymer enamel coating – helps protect the surface and improves aesthetics.
    • Screw fastening – simple and clear installation method.
    • Universal use – suitable for various ventilation and air distribution systems.

    Cons / Limitations

    • Suitable for D150 systems only – other duct diameters require a different sized connector or adapter.
    • Requires a solid surface – the mounting location must support the weight of the duct and connector.
    • Requires additional sealing – joint areas may need sealing to reduce air leakage.
    • No airflow regulation – this is a mounting/connection element, not a damper or register.
    • Steel can be vulnerable in aggressive environments – in highly humid or corrosive areas, consider additional protection.

    Installation and usage notes

    The wall connector is a ventilation system mounting and connection component; therefore, before installation, it is important to evaluate duct diameter, airflow direction, mounting surface, and sealing requirements.

    • Check the diameter – the connector is designed for a D150 / 150 mm duct.
    • Mount to a stable surface – wall, ceiling, or other plane capable of supporting duct weight.
    • Use appropriate screws depending on the installation surface type.
    • Seal the connections if airflow efficiency and minimal losses are important in your system.
    • Avoid mechanical damage – thin sheet steel can deform from strong impacts or improper installation.

    Quick selection guide

    D150 wall connector for duct – a suitable choice when you need to attach a 150 mm circular duct to a wall, ceiling, or other flat surface. This is a white steel connector with a 300x300 mm mounting flange and a polymer enamel coating.

    Suitable when you need to:
    • connect a D150 duct to a wall or ceiling;
    • utilize a 300x300 mm mounting flange;
    • install a ventilation system connection point;
    • use a white steel connector with enamel coating;
    • attach a duct to a flat surface using screws.
    Check before installation:
    • is your duct diameter 150 mm;
    • is the mounting surface sufficiently stable;
    • is additional sealing required;
    • are screws selected according to wall or ceiling material;
    • will the connector be exposed to a highly corrosive environment.
    Important reminder:
    This part is a duct mounting / connection fitting. It does not regulate airflow, act as a damper, and does not replace ventilation grilles or air valves.

    FAQ – Frequently Asked Questions

    What is this wall connector for?
    This connector is intended for attaching a circular D150 duct to a wall, ceiling, or other flat surface within a ventilation or air distribution system.
    What duct diameter does it fit?
    The connector is intended for a 150 mm / D150 diameter duct.
    What are the connector dimensions?
    The connector height and width are 300x300 mm, and the mounting diameter is 150 mm.
    What material is the connector made of?
